Chiller Noise No Longer Problem After Acoustifence Barrier Installed

Leave a comment

Installation of a 24-foot noise barrier utilizing Acoustifence outdoor sound abatement material at the new Sheboygan Festival Foods store is complete, ending complaints from nearby residents over extreme levels of noise leaking from the store’s industrial refrigeration chillers into the community.

Folks in Sheboygen were celebrating when the popular Wisconsin-based Festival Foods grocery chain opened the 70,000 square foot mega store here on September 16, 2011. Less than two weeks later, the community’s warm welcome had grown icy as neighbors began to complain about noise from the store’s industrial refrigeration chiller that was so loud, it violated the city’s noise ordinance.

Festival Foods enlisted the help of Acoustical Engineer Eric Wolfram of Milwaukee-based Scott R. Riedel & Associates, LTD, who consulted with Acoustiblok’s Jay Boland to choose Acoustifence noise barrier material, a product of Acoustiblok, Inc. of Tampa Florida, to bring the decibel level down below the legal threshold and restore peace and quiet to the neighboring community.

When Wolfram first investigated the site in September, decibel readings ranged between 78.4 and 90.7, loud enough to be a risk for noise-related health problems to nearby residents and workers, had they been subjected to the noise over time. The Sheboygan Department of City Development demanded the level be reduced by at least five decibels, Wolfram said.

“The existing refrigeration pump and motor systems produce extreme noise levels,” Wolfram said. “This noise reverberates within the sheet-metal paneled enclosure interior and escapes through several different exhaust and ventilation openings.

“Additional noise was generated by the cooling and exhaust fans mounted above the enclosure.”

Working with sound consultants from Acoustiblok, Inc., Wolfram designed a two-step solution, creating a barrier with Acoustifence noise deadening material to block noise around the massive system, and incorporating another Acoustiblok product, QuietFiber, to help reduce sound from reflecting off of the taller adjacent building behind the chillers.

Minimal structural changes were required, as the â…›- inch Acoustifence was easily attached to an existing chain link fence and the outdoor-rated QuietFiber with a perforated metal cover was capconed to the building.

The results were better than Wolfram had hoped, with decibel levels reduced to 57.3 the moment the barrier was in place – well below the City’s legal threshold, and more than 20 decibels lower than before the Acoustiblok products were installed. Neighbors are no longer bombarded with the irritating chiller noise, now replaced with the ordinary ambient sounds that existed before.

“Sounds from local traffic and roadways exceeded that of the compressor equipment after installation of the Acoustifence and QuietFiber products,” Wolfram said.

Lahnie Johnson, founder and president of Acoustiblok, Inc., applauded Festival Foods’ quick action in addressing the noise complaints right away, stating that the product combination was the perfect solution for this particular type of noise challenge.

“The Acoustifence and QuietFIber treatments were the perfect solution for the Festival Foods chiller noise, as both of these materials are designed to hold up in inclement weather, and as you can see from the results, they do their job well beyond everyone’s expectations,” Johnson said. “The Acoustifence and Quiet Fiber are also substantially less costly than attempting a structural enclosure solution.”

Acoustiblok Creates Damped, Expandable Acoustical Envelope in New York ITB Recording Studio

Leave a comment

Acoustiblok noise abatement material was installed in the nearly completed Artist Workshop Studios recording facility, an in-the-box (ITB) studio designed and built by Artist Workshop Studios owner Tom Donofrio. Acoustiblok was chosen to provide a sound barrier for the small, 12 foot x 12 foot basement studio that could drop decibels levels within the space and provide a neutral acoustical environment for recording.

Donofrio, an electrical engineer, and musician who has built recording studios in the past using different sound deadening materials, chose Acoustiblok for his newest project after consulting with Marilyn Myers of Acoustiblok, Inc., because of its sound damping and noise blocking qualities, as well as its thin, flexible structure that adds no volume to walls within the studio space. Attached to the studs before drywall is hung, Acoustiblok performs without the need to add layers of rigid drywall or modified drywall, a method Donofrio used in the past with mixed results and significant floor space reduction.

“I was looking for a product that would lower the decibels in the studio without taking up any additional space,” Donofrio said. “I was able to achieve the neutral acoustics desired in the space, which makes me extremely happy.

“I didn’t want a sound quality that was too dead or too live, so the Acoustiblok turned out to be an excellent choice.”

Donofrio and a friend were able to hang the 3mm Acoustiblok on the newly framed stud walls within the studio space, including cutouts around a window and electric sockets, and seal the seams according to installation recommendations, all in less than four hours.

The Artist Workshop Studios recording space was built for Donofrio to indulge his own talents as an acoustical guitarist and vocalist, and to be made available to artists on a budget who need an affordable studio with high quality production equipment and the expertise of a seasoned technician to record a song or album.

“Acoustiblok is a perfect choice for establishing sound quality within a sound recording studio like this one,” said Lahnie Johnson, president and founder of Acoustiblok, Inc.

“Unlike additional drywall or other solid rigid materials used for sound reduction, the 1/8-inch heavy, limp Acoustiblok allows the room to be a damped, expandable acoustical envelope. As such, a studio or home theater has less reflection and actually sounds significantly better.”

Quiet Fiber® Used to Quiet Industrial Generator Noise at Galleria 360 in Santo Domingo

Leave a comment

Installation of 18,000 square feet of non-fiberlass Quiet Fiber® noise abatement material has been completed in the massive generator room of the newly constructed, 750,000 square foot Galleria 360 mall in Santo Domingo.

Quiet Fiber, a product of Acoustiblok, Inc. in Tampa, Florida, was installed on the ceiling and walls of the mall’s generator and substation rooms. These rooms house the industrial emergency generators necessary to keep power running in this coastal area of the Caribbean, plagued by frequent power outages.

The Galleria 360’s industrial generators, installed by Santa Domingo-based Edelca, are a staple in this island republic. Edelca owner Carlos Montos, Edelca consulted with Jay Boland of Acoustiblok, Inc., and used Quiet Fiber on the project after achieving excellent results with Quiet Fiber on a similar project at the La Sirna Superstore in the eastern coastal town of Higuey, Dominican Republic.

“Even though Quiet Fiber is not the least expensive product on the market, I keep coming back to it because the results beat all the competitors’ noise deadening products with double the noise insulating qualities,” Montos said. “The customer on this job wanted to install a double layer of a different product but I convinced him to try the Quiet Fiber.

“I’ve been designing and installing these emergency generators for 20 years, and I have never had the results from other noise abatement products that I have with Quiet Fiber, and now I’m trying to use it everywhere.”

Montos says noise from these industrial generators on which the island has become dependent in order to maintain consistent power is a major problem plaguing businesses and residential property owners when the generators are running. Not only is generator noise bad for business, but its constant drone can cause permanent hearing loss. Another important consideration in the selection of soundproofing material is its fire resistance.

Recently in Santo Domingo a serious fire started in a generator room, and the existing foam sound proofing material was a prime contributor. The fire caused Montos to search for a new fireproof solution. Quiet Fiber is fire resistant even at 2,000 degrees.

“The noise levels are almost unbearable, so you need to have an adequate level of soundproofing in place when they are running,” Montos said. “I always install noise absorbing material wherever I install my generators, and Quiet Fiber is the best soundproofing product we’ve ever used.”

Montos and his crew were able to easily cut the Quiet Fiber to fit around electric conduits, and secured the material to the walls and ceiling with standard insulation stick pins.

The sound deadening qualities of Quiet Fiber will help to protect the mall’s employees, and streams of tourists and local residents from the high volume industrial noise caused by the generators when they are operating.

Lahnie Johnson, president and founder of Acoustiblok, Inc., says that the application of Quiet Fiber in the Galleria 360 generator and substation rooms was exactly what was needed for addressing the high decibel, reverberant sound emanating from the concrete walls.

“Quiet Fiber was designed with this type of hot, humid environment in mind,” Johnson said. “When you’re addressing solid surface noise issues, which in this case with concrete walls, you need a product with proven maximum sound absorption, high temperature rating for fire blocking, and hydrophobic (resistant to moisture).”

Acoustifence Installed at Coca-Cola Plant Cuts Industrial Noise Pollution Almost in Half at Neighboring Residences

Leave a comment

Coca-Cola has completed installation of Acoustifence® noise barrier fencing along the west perimeter of its Bay City plant, bringing to an abrupt halt those noise issues that had been plaguing neighbors in the surrounding community and attracting local news organizations as the outcry from area residents grew.

Architect Jack Zelazny of Dearborn, Michigan, acting as a consultant to Coca Cola’s contractor Kirco Manix, chose Acoustifence noise barrier fencing for the core of the 300 foot wide noise barrier project designed to alleviate noise from idling delivery trucks at the plant that had been plaguing neighbors in the South End Community.

Zelazny said the initial plan was to construct a 30 foot acoustical metal fence along the perimeter roadway to address the problem, but he nixed the idea in favor of something significantly less expensive and more aesthetically pleasing to the community’s residents.

“I didn’t think it was appropriate for the neighbors to have to stare at a 30 foot industrial metal fence from their small residential yards,” Zelazny said. “I really wanted to find something more organic and natural.”

After researching sound barrier fencing options, he found Acoustifence, a product of Acoustiblok, Inc. in Tampa Florida, and discussed his options with acoustical consultant Paul Getts of Acoustiblok. After conferring with Getts, Zelazny moved ahead with construction of a grass covered, 300 foot wide berm that incorporated a nine foot high Acoustifence barrier and landscaping for an attractive roadside aesthetic. The project was completed in the final weeks of December, and both company officials and neighbors rang in the New Year with their new found peace and quiet.

“The Acoustifence went up flawlessly, and it’s not unpleasant to look at,” Zelazny said. “When we covered it with the dark green acoustical fabric covering it looked natural and organic, as we had hoped.

“But the real surprise was the immediate impact it had on the noise.”

Zelazny said the plant noise measured at 89 decibels before installation of the Acoustifence began, and registered at 68 decibels immediately after the Acoustifence went up. His hope was to lower the noise by 20 decibels, a figure that was exceeded at the plant, and more than doubled at the neighboring residence as soon as the Acoustifence was put in place. A reading taken at the adjacent residential property registered in the low to mid 40 decibel range.

“It exceeded my expectations, I think it exceeded everyone’s expectations,” he said.“The people at Coca Cola are happy with it, and most importantly the neighbors in the surrounding community are happy with it.

“I couldn’t speak more highly of it.”

Lahnie Johnson, president and founder of Acoustiblok, Inc., said that the application of Acoustifence in the bottling plant’s noise barrier berm was the soft drink company’s best alternative for significantly reducing noise, and respecting the surrounding community’s call for peace and quiet.

“I think Coca Cola acted quickly and responded to the area’s residents as a good corporate neighbor should,” Johnson said. “It’s particularly important that they sought out a serious noise blocking option while respecting the fact that neighboring residents would be living with whatever solution they chose, and viewing it every day – some from their own back yards.”

Acoustifence was designed to address outdoor noise pollution in residential communities, or any community that cares about its appearance.”
